摘要： A guide wire is disclosed, which is capable of reducing an unintended deviation in a guide wire position while preventing an occurrence of discomfort with respect to usability. The guide wire has a flexible core wire, and has a distal core portion, a main body portion, and a rigidity changing portion that gradually decreases in rigidity from the main body portion toward the distal core portion. The rigidity changing portion includes a first tapered portion continuous with a distal end of the main body portion, a second tapered portion continuous with a distal end of the first tapered portion, and a third tapered portion continuous with a proximal end of the distal core portion. A boundary portion between the first tapered portion and the second tapered portion is located in a range of 300 to 400 mm from a foremost distal end of the distal core portion.

摘要： The present invention relates to a male contraception apparatus for obtaining a time-limited sterility of a male mammalian individual. The apparatus comprises a restriction device adapted to restrict the lumen of a vas deferens of the mammalian, and a controller operable to control the restriction device to restrict the lumen of the vas deferens during a controlled period to prevent sperms from reaching the urethra of the mammalian. The apparatus further comprises an implantable constriction device configured to gently constrict at least one portion of a tissue wall of the vas deferens to restrict the lumen of the vas deferens such that the flow of sperms in the vas deferens is restricted, and a stimulation device configured to stimulate the constricted wall portion of the tissue wall.

摘要： Methods and apparatuses for pumping blood within a blood vessel are described. The methods and apparatuses can be used for renal decongestion by pumping blood through the kidney(s), thereby increasing a pressure gradient across the kidney(s). The apparatuses can include one or more inflatable elements that can be repeatedly inflated and deflated to cause a pumping action within the blood vessel. In some embodiments, the one or more inflatable elements are positioned within one or more stents.

摘要： Disclosed embodiments include apparatuses, systems, and methods for assessing collateral ventilation. An illustrative embodiment includes a flexible insertion catheter device includes an outer tube having an inner diameter. The outer tube includes a plurality of ports at a distal end and an occlusion device filling port located proximal from the plurality of ports. Also, the flexible insertion catheter device includes an inner tube receivable within the outer tube. The inner tube includes a flow lumen and an outer diameter less than the inner diameter of the outer tube. The flexible insertion catheter device further includes an occlusion device attachable to the outer tube and configured to selectively seal a bronchial passageway to occlude a lobe of a lung.

摘要： Systems and methods and devices are provided for treating conditions such as heart failure and/or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patient's superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patient's Frank-Starling curve towards healthy heart functionality and improved cardiac performance. The occlusion device may include a lumen obstructed by a relief valve that may permit fluid flow through the occlusion device to release an excessive build-up of pressure.

摘要： Exemplary embodiments of devices and method for affecting at least one anatomical tissue can be provided. A configuration can be provided that includes a structure which is expandable (i) having and/or (ii) forming at least one opening or a working space through which the anatomical tissue(s) is placed in the structure. For example, the structure, prior to being expanding, can have at least one partially rigid portion. In addition, or as an alternative, upon a partial or complete expansion thereof, the structure can be controllable to have a plurality of shapes. Further, the structure can be controllable to provide the working space with multiple shapes and/or multiple sizes.
